To all whom it may concern:

Be it known that I, HENRY E. McGowAN, a citizen of the United States, residing at New York, in the county of Kings and State of New York, have invented new and useful Improvements in a System of Cooling for Coir- (lensing Steam Plants, of which the following is a specification.

, My invention relates to cooling system for steam plants and especially condensing steam plants, regardless of whether such plants are used for the development of power for evaporation or for any one of a number of similar uses.

The invention consists in providing various structural details whereby certain economies are brought about and functions performed not heretofore operated in conjunction. These objects are obtained by an arrangement of apparatus such as shown in the diagrammatic View forming a part hereof which serves to illustrate one method by means of which the invention may be carried into practice.

The hot well A which preferably is plural, or which may contain a plurality of chambers a, a, a, is introduced between the cooling tower B and the condenser C of the ongine D. In the base, or suitably connected with the cooling tower B, is a reservoir E connected by pipe F for supplying the condenser C, an extraneous supply being furnished by water pipe controlled by valve G actuated by the float G, suitably placed, for instance, in the hot well and responsive to differences in level of the water in the reservoir with which it cooperates. A circulating or liftin pump H draws its supply from hotwell A, y means of pipe H, it bein under stood that the drawing is simply iagrammatic, as no lift against gravity need be encountered in the supply-to pump H, Pipe H furnishes the water to the upper part 01 the cooling tower B. This may be of any convenient form. Any cooling device may be employed in lieu of the tower B shown in the drawing. In one of the cavities or in the hollow wall forming a dam between cavity a a, is an oil removing apparatus which in the present instance is represented by the device This consists of a mat of oil-absorbiru material, for instance excelsior or wood shavings, through which the water readily flows, leaving the oil behind, and when 010 ged, this matrass-likc device may be .slig tly raised by pulley or device 1', thereby} functionasuch forinstance as oil boiler feed system K having pipes K and K leading from the heater K to the boiler J.

.The fan L or other cooling means employed in connection with the tower is driven by motor M whereas the circulating pump is driven by motor M and these motors are each controlled by the rheostats It and it and switches S and S. These rliieostats, while they are independently controllable, may be moved simultaneously and either or both may be automatically controlled as by the thermometric device T, which may serve to operate an intermediate energizing mechanism such motorm controlled by reversing switch it of the well known construction This operates on the worm gear 0 controlling the rheostats in response to the variation in temperature of the water or contents of tank E. An overllow pipe B between the tower B and the hot well A is shown at the proper level and in proper relation to each of these elements.

The use and operation of my device will'be Attention apparent from the foregoing. may be, however, called to the fact that y use of my invention a comparatively small cooling tower may be employed, because arrangement is such that the water may passed through such tower several times as" rapidly as it is fed to the condenser C. II tofore it has been the practice to pass the cooling water for the condenser in a single circuit from the condenser to the cooling tower and back, but in the present device a multiple circulation is provided whereby water flowing through the tower may be in excess of that furnished to the'condenser, overflow betweenthe tower and supply res-- emu 'ervoir a which may be a part of the hot well being. supplied, as shown in the drawing. Thus we have a multiple Water circulation between the hot well and the tower, in com-- bination with a'roservoir for supplying the condenser connectedwith the ton er, which is constantly more and more cooled. Gi er and above this, the hot well is mu? in its structure and the various con which may be either separate or single structure, are made toperie steam plants, a condenser, a hot well for between a, and a and again such for instance ,1 as heat insulation'as'between compartment (1, i .and (1, whereby the lornu-r is ltept the hotl tcr oning to the multiple circulation to the towel l5 and l1o111 which eon1par1n1ent the boiler l'eed deriu-s its supply by means oi pipe ii, us is readily und er discharge l rozn lin' condenser entering the lirst sections the multiple wellv The boiler l'ced'is supplied with the additional heater .hi and the extraneous water supply entering the sys1e111 at or near the condenser is made automatic and responsive to the water levels in some suitable tank connected 1 with the system, as for instance. the hot well or one of its co11'1partn1e111s,as show 11 through the device ol the lloat (.l and valve U.

in cold weather it is understood that not as much cooling notion is necessary through the cooler or fan L, nor is the 11ml: iple circulationrequiredtol 11 s rigorous. 'l'lnzrclore, both ol'these devices may be made to absorb less power from the system. This may be manually regulated or autonlatically, as shown by the thernio .1etric device '1 operating to control the motors M and M or either of them, either directly or l1rongh the intermediary ol the power nrraogenlont comprising niotor mand nn-eha'nisin o.

it will readily be understood that many of the details may be varied and their arrange' nient may be altered without departing from the spirit of the invention.
